Git

Git is a distributed version control system designed for tracking changes in source code and enabling collaborative development workflows.

Key Concepts

• Repositories - Project containers with complete history
• Branches - Parallel development lines
• Commits - Snapshots of project state
• Merging - Combining changes from different branches
• Remote Repositories - Shared repositories for collaboration

Security Considerations

• Signed Commits - GPG signing for authenticity verification
• Access Control - Repository permissions and branch protection
• Secret Management - Keeping credentials out of repositories
• Audit Trail - Complete history of all changes
• Code Review - Pull request workflows for security review

DevSecOps Integration

Git is foundational to DevSecOps practices, enabling infrastructure as code, configuration management versioning, security policy as code, and automated security testing in CI/CD pipelines.
